Oh, you know, the usual. Nothing special.
Nuwa's Berserk gets a lot damage in, but if I do a proper run, I probably need to not use that. It would probably be more ideal to get Marduk to burst twice, and it makes Shingen less RNG-y (only needs 3 hits in two turns instead of 4). Not using Berserk is a big damage loss from two turns, though.
